BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a system and method for displaying a menu. More particularly, the present invention relates to a system and method for displaying a menu having an icon, provided when displaying image data stored upon a recording medium on a menu screen under GUI (Graphic User Interface) circumstances in an AV (Audio and Video) device, the AV device having a hard disc drive or a flash memory as the recording medium.

2. Description of the Related Art

Developments in image data digitization and condensation technologies have resulted in image recording/reproducing devices which are capable of reproducing image data stored upon an optical medium such as a CD-ROM or DVD title. These optical media do not deteriorate significantly even with long use, and can record high quality images and multichannel audio data (for example, 5.1 channel audio). An optical medium such as a DVD title, can record image data and audio data of file sizes up to hundreds of Mbytes and even as large as several Gbytes, and an image recording/reproducing device has been introduced which reproduces just the optical medium. The conventional image recording/reproducing device using an optical medium provides a basic function for reproducing an image data stored upon the optical medium. An OSD (On Screen Display) menu of an image recording/reproducing device can be provided and typically comprises a menu for setting an aspect ratio of a screen, for example, 4:3 and 16:9, when reproducing a DVD title, a menu for setting a format such as NTSC/PAL of image data to be transmitted to a display device such as a television connected with the image recording/reproducing device, and a menu for setting an output form such as Dolby digital and PCM for audio data. The menus are used to define how to reproduce image data or audio data stored at a DVD title or a CD-ROM title simply based on the MPEG-2 format, but if image data is stored upon a certain recording medium such as a flash ROM or a hard disc drive built into an AV device, it is difficult to recognize the content of the image data.

Accordingly, a need exists for a system and method for displaying a menu for easily recognizing image data content with respect to image data recorded in an image reproducing device which is capable of recording/reproducing digital image data.

SUMMARY OF THE INVENTION

The present invention has been developed in order to solve the above and other problems associated with the conventional arrangement. An aspect of the present invention is to provide a system and method for displaying a menu for use in an image reproducing device which is capable of recording/reproducing digital image data, by which, recorded image data can be easily recognized.

According to another aspect of the present invention, a menu displaying system and method is provided for editing image data in an AV (Audio and Video) device which has a recording medium capable of storing image data and audio data, and which is capable of reproducing image data and audio data. The menu displaying method comprises steps for displaying icons and additional information corresponding to the image data stored upon the recording medium, selecting one of the icons displayed, and reproducing image data corresponding to the selected icon.

The step of selecting one of the icons may further comprise steps for locating a cursor on the icon, and calling image data, stored upon the recording medium, from an address in which image data is stored corresponding to the icon under the cursor.

When the cursor is moved out of the icon, the reproducing of the image data corresponding to the icon is stopped.

The step of reproducing the image data further comprises steps for reproducing the image data on the screen at selected speeds, ranging from slower to faster.

The step of reproducing the image data further comprises steps for reproducing the icon which occupies a certain area on the screen.

The icon upon which the cursor can be placed, displays a frame of the MPEG image data stored, preferably a first frame or I frame, on the screen.

DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

Certain embodiments of the present invention will now be described in greater detail with reference to the accompanying drawings.

In the following description, same drawing reference numerals are used for the same elements even in different drawings. The matters defined in the description such as a detailed description of construction and elements, are provided to assist in a comprehensive understanding of the invention. Also, functions or constructions which are well known to those skilled in the art are not described in detail since they would obscure the invention in unnecessary detail.

FIG. 1 is a block diagram of an exemplary DVD reproducing device illustrating an AV device to which a menu displaying method can be applied for reproducing an image according to an embodiment of the present invention.

The depicted DVD reproducing device comprises a switching part 10, a MPEG encoder part 20, a HDD (hard disc drive) 30, a Flash ROM 40, a control part 50, a RAM 60, a light receiving part 70, a decoder part 80, and an optical media player 90.

The switching part 10 receives various external image data/audio data, and outputs image data from the decoder part 80 to outside devices, such as a monitor screen. The switching part 10 receives external signals such as a broadcast signal, and component and composite signals sent from a video (not shown), and selectively connects each to a function block of an image recording/reproducing device. For example, when the external signal sent from an external device such as a video, is a component or composite signal, the switching part 10 transmits the signal to the MPEG encoder part 20.

The MPEG encoder part 20 converts analog image data to digital image data, and compresses the digital image data into an MPEG format such as MPEG-2 format. In general, image data in MPEG format is compressed such that the requirement for storage space can be reduced when storing upon a recording medium such as the HDD 30.

The HDD 30 stores the MPEG image data/audio data as a file. The MPEG image data/audio data, among the image data received at the switching part 10, can be stored as they are received. For an exemplary implementation of the present invention, the above embodiment depicts the HDD 30 as storing MPEG-2 image data as a file. However, this should not be considered as limiting. The HDD 30 may store data in MPEG-1, MPEG-2, and MPEG-4 formats. Furthermore, in the exemplary embodiment, the MPEG encoder part 20 and the decoder part 80 encode and decode data according to an MPEG-2 format, however, each may encode and decode data in MPEG-1, MPEG-2 and MPEG-4 formats.

The Flash ROM 40 stores an operating system for operating a DVD reproducing device, and further includes application programs for displaying image/audio files of the HDD 30 and additional information in GUI (Graphic User Interface) menu form on a screen. The Flash ROM 40 further includes application programs for editing and displaying the image data/audio data of the HDD 30 via the displayed menu.

The control part 50 stores MPEG data output from the MPEG encoder part 20 at the HDD 30, or transmits image data/audio data stored at the HDD 30 to the decoder part 80. The control part 50 performs an application program stored at the Flash ROM 40, displays an icon corresponding to the image data file of the HDD 30, and reproduces on a menu, the icon selected by a control signal (not shown) received from a remote controller (not shown).

The RAM 60 loads a file when the control part 50 edits the file stored at the HDD 30. That is, the control part 50 does not directly edit a file stored at the HDD 30, but the RAM 60 edits the file, and the edited file is then stored again at the HDD 30.

The light receiving part 70 receives a control signal (not shown) generated from a remote controller (not shown), or from a setting key (not shown) built in the image recording/reproducing device for controlling various tasks, for example, converting channels and adjusting volume and image quality of the image recording/reproducing device, and then transmits the control signal to the control part 50.

The decoder part 80 receives MPEG image data stored at the HDD 30 via the control part 50, and converts the data into a video format such as NTSC/PAL. The converted signal can then be reproduced at an image display device such as a television (not shown). The optical media player 90 reads image data and audio data from a DVD title, and transmits the data to the control part 50. The image data and audio data transmitted to the control part 50 are either stored at the HDD 30, or transmitted to the MPEG decoder part 80 to be reproduced.

FIG. 2 is a view of an exemplary remote controller of the DVD reproducing device of FIG. 1. The remote controller 100 has a menu key 101 for instructing the loading, opening, and closing of a menu screen, and left, right, up and down direction keys 102, 103, 104, and 105, respectively, for instructing movement among menus on the menu screen. The enter key 106 is provided for selecting a menu, and the return key 107 is provided for returning the present screen to a previous screen.

Additional keys are provided for operating an image recording/reproducing device (not shown) and an image display device (not shown) such as a television. The functions of these keys can be easily recognized by markings indicated adjacent to or upon each of the keys, and therefore, a detailed description of each of the remaining keys will be omitted.

FIG. 3 is a view of an exemplary initial menu guide screen which can be provided when the menu key 101 of FIG. 2 is selected. In the example shown in FIG. 3, the digital recorder menu 201 is also selected which results in a sub menu display 201 a.

When the menu key 101 of the remote controller 100 is pressed, a corresponding control signal (not shown) is transmitted to the light receiving part 70, and the control part 50 calls an application program stored at the Flash ROM 40 to display the menu in GUI form on the screen.

The displayed menu 200 comprises a digital recorder menu 201 for managing data stored at the HDD 30, a DVD player menu 202 for reproducing a DVD title inserted in the optical media player 90, a juke box menu 203 for reproducing or storing a music CD at the HDD 30 when a CD-DA standard music CD is inserted, a photo album menu 204, and a set up menu 205.

A sub menu 201 a is displayed on the screen when the digital recorder menu 201 is selected. As depicted, the sub menu 201 a of the digital recorder menu 201 comprises a Program List menu 210 showing a list of image data stored at the HDD 30, a Parental Lock menu 220 for limiting viewer's access to a certain program such as an adult program, an Edit menu 230 for editing image data stored at the HDD 30, and a Recording menu 240 for recording a broadcast program according to a preset time.

FIG. 4 is a view of an example of a menu displayed on the screen when the program list menu 210 is selected on the initial menu guide screen of FIG. 3. The program list menu 210 comprises an icon menu 211 of icons 211 a to 211 d corresponding to programs stored at the HDD 30, a Title identification part 212 for indicating a program title corresponding to each icon 211 a to 211 d, a date identification part 213 for indicating the stored time of each program at the HDD 30, and a reproducing length time identification part 214 for indicating a reproducing time of each program. Each of icons 211 a to 211 d is displayed on the first start frame, that is, an I frame, of MPEG image data stored at the HDD 30, and has information on a start address of the corresponding program stored at the HDD 30.

FIG. 5 is a flow chart illustrating a method for displaying a menu having an icon according to an embodiment of the present invention. In order to display the program list menu 210 of image data stored at the HDD 30 on the screen, the program list menu 210 should be selected on the initial menu guide screen 200. When the menu key 101 is pressed on the remote controller 100, a control signal (not shown) generated from the remote controller 100 is transmitted to the light receiving part 70, and the control part 50 detects the transmission at step S300, and displays the initial menu guide screen 200 on the screen as shown in FIG. 3 at step S400.

When a cursor is located on the program list menu 210 on the initial menu guide screen 200 by the use of direction keys 102 to 105 and the enter key 106 is pressed, a control signal generated from the remote controller 100 is transmitted to the light receiving part 70. The control part 50 detects the transmission at step S500 and displays the menu 210 as shown in FIG. 4 on the screen at step S600. The icons 211 a to 211 d are displayed in forms of still images on the menu displayed on the screen and which correspond to programs stored at the HDD 30. The title, storing time, and reproducing time of the programs are indicated adjacent to each of icons 211 a to 211 d.

At step S700, when the direction keys 102 to 105 are pressed to locate a cursor on one of a plurality of icons 211 a to 211 d on the program list menu 210 on the screen as shown in FIG. 4, an icon under the cursor calls a program stored at the HDD 30 at step S800. The still image of the icon represents the first start frame, that is, an I frame, of a program stored at the HDD 30, and specifically, when a cursor is located on one of the icons 211 a to 211 d, a corresponding program is loaded from the HDD 30 to be reproduced at step S900. The size of the image data provided in response to the call of an icon and reproduced on the screen is substantially the same size as the icons 211 a to 211 d. That is, the selected icon of icons 211 a to 211 d displayed on the program list menu 210, is reproduced and displayed as moving images within the same position. When an icon, for example 211 a, under the cursor is reproduced as a moving image, and the cursor is moved to another icon, for example 211 b, the reproduction of the moving images corresponding to the icon 211 a is stopped, and a moving image is reproduced on the screen corresponding to the icon 211 b currently under the cursor.

The icon 211 a, which is no longer reproduced, may then again be displayed on the screen as a still image of the initial I frame of the program corresponding to the icon 211 a.

In order to reproduce image data in the areas of icons 211 a to 211 d slower or faster, the direction keys 102 and 103 of the remote controller 100 may be pressed to set desired reproduction speeds, such as 2 times an original speed, 4 times an original speed, or ½ times an original speed. For example, if the direction key 102 is pressed once, ½ times an original speed may be set as the reproduction speed, and if the direction key 102 is pressed once more, ¼ times an original speed may be set as the reproduction speed. If the direction key 103 is pressed once, 2 times an original speed may be set as the reproduction speed, and if pressed once more, 4 times an original speed may be set as the reproduction speed.

If a user desires to know which program is stored at the HDD 30, the user may simply locate a cursor on the icons 211 a to 211 d in which the first frame (I frame) of each program is displayed, such that the contents of each program corresponding to each icon are displayed on the screen, and the user can then easily observe the contents of the program.

As described above, a program stored at an AV device having a recording medium such as a hard disc drive, is reproduced in a menu screen according to an embodiment of the present invention, and therefore, image data stored at the AV device can be easily observed.
